Problems solved by technology

However, the entire modeling process is entirely dependent on manpower, and the modeling time is long
Moreover, in the later design or construction process, if it is necessary to modify and adjust the 3D model, it may be necessary to re-model some component models, which will still consume a lot of time
In addition, when the component model is rotated and moved, it is prone to deviation caused by manual operation

Embodiment Construction

[0038] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the following embodiments will specifically illustrate the three-dimensional rapid modeling method of the traffic infrastructure of the present invention in conjunction with the accompanying drawings.

[0039] The 3D rapid modeling method of transportation infrastructure can quickly obtain a 3D model by setting and adjusting the parameters of the disassembled and assembled components, rotating and moving the components, which can greatly improve the modeling speed and avoid deviations caused by manual operations. And it is convenient for later modification of the model. Such as figure 1 As shown, the 3D rapid modeling method of transportation infrastructure includes the following four steps:

[0040] Step S1, according to the design drawings, determine the positioning lines of various components in the transportation infrastructure, split each compone...

Abstract

The invention provides a three-dimensional quick modeling method for transportation infrastructure. The method comprises the steps: splitting all members of a transportation infrastructure modeling entity into a plurality of assembly members, obtaining the positioning point parameter and space angle parameter of each assembly member, achieving the rotation and moving of each member through the setting and adjustment of the parameters, and a building a three-dimensional model. Therefore, the method can effectively avoid the deviation caused by manual operation, greatly shortens the modeling time, guarantees the quick adjustability of modeling, and meets the demands of construction management.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, and in particular relates to a three-dimensional rapid modeling method for traffic infrastructure. Background technique [0002] With the rapid development of my country's economic construction, the construction of traffic infrastructure such as roads, bridges, and tunnels is constantly being strengthened, and its engineering construction and management are crucial. In order to meet the needs of construction management, it is necessary to establish a solid 3D model of the transportation infrastructure. [0003] At present, by collecting design drawing information, the modeling entities of traffic infrastructure such as roads, bridges, and tunnels are divided into multiple components, and the models of each component are established one by one. One of the main models is selected as a fixed model, and the other components are After the model is rotated and moved, it is spliced ​​i...
